Harden has been diagnosed with a concussion and has yet to be cleared to play.

Here’s the NBA’s statement:

“The concussion suffered by James Harden demonstrates the danger posed by violent acts of this kind, particularly when they are directed at the head area,” NBA commissioner David Stern said in a statement. “We remain committed to taking necessary measures to protect the safety of NBA players, including the imposition of appropriate penalties for players with a history of on-court altercations.”
